Clone TFD10
Isotype IgG1
Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
3. Please refer to us for technical protocols.
Purification Purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name DP-1
Background DP-1 and DP-2 are transcription factors which form heterodimers with several members of the E2F family. DP-1 binding to E2F is often required for interaction between E2F and the retinoblastoma family of proteins (Rb, p107 and p130), which restrict E2F/DP complexes to the cytoplasm. These E2F inhibitors are phosphorylated by complexes which are formed during the cell cycle, e.g., cyclin-cdk complexes. Phosphorylation of RB or other inhibitors releases the E2F/DP complex to enter the nucleus, thus providing temporally regulated activation of E2F responsive genes. While some E2F proteins can act alone, formation of a DP-1 heterodimer provides enhanced DNA binding and transcriptional activity to E2F. E2F-DNA binding sites have been identified in the promoter regions of genes important for growth regulation, e.g., c-myc, N-myc, cdc2 and cyclin A as well as within genes which are important for DNA synthesis, e.g., DNA polymerase alpha and thymidine kinase. Activation of specific gene(s) may also be dependent on the formation of distinct DP/E2F complexes. Cotransfection studies demonstrate specific interactions between E2Fs and DP-1 or -2. DP-1 binds to E2F-1 through -4, while DP-2 is specific for E2F-4. DP-1 may also play a role as a proto-oncogene in cooperation with Ras proteins, a mechanism, which is independent of E2F. DP-1 has a molecular weight of 52-55 kDa by SDS-PAGE. The TFD10 antibody recognizes an epitope between amino acids 83-204 of human DP-1. The specificity of the antibody was verified by immunoprecipitation of in vitro translated DP-1 protein and by western blot analysis of cell extracts.
Molecular Weight 52-55 kDa
Application Notes Clone TFD10 is useful for western blot (1-2 µg/ml) of human DP-1. Several human cell lines may be used as a positive control for this application includingL HeLa, cervical carcinoma (ATCC CCL-2), RD, Rhabdomysarcoma (ATCC CCL-136), Daudi, Burkitt lymphoma (ATCC CCL-213) and CEM peripheral blood T cell lines (ATCC CCL-119).
